## What you need to know

Things to remember:

• You can change the order of times tables to make them easier.
• We can split up times tables to make them easier.

Tips:

0 Times Table: When we multiply by 0 the answer is always 0, $2361.35562\times0 =0$

1 Times Table: When we multiply by 1 the number doesn’t change. $1411.245\times1=1411.245$

2 Times Table: The 2 times table is just doubling!

3 Times Table: No tricks to it, you just need to learn them!

4 Times Table: If we compare the 2- and 4-times tables, we can see that the 4 times table is just double the 2 times table. We double and double again!

$$11\times4=11\times2\times2=22\times2=44$$

5 Times Table: The 5 times table always ends in a 0 or a 5.

6 Times Table: $6=3\times2$. If you learn the 3 times table, you can use this and then double to get the 6 times table!

$$5\times6=5\times3\times2=15\times2=30$$

7 Times Table: No tricks to it, you just need to learn it!

8 Times Table: We can swap the order to make it easier. If we wanted to find $5\times8$ we could instead do $8\times5=40$.

Also, notice that the 8 times table is just double the 4 times table. So, we can double, double, and double again.

$$11\times8=11\times2\times2\times2=22\times2\times2=44\times2=88$$

9 Times Table: We have a couple of tricks here:

The numbers in the 9 times table add together to make 9

If we look at the 9 times table in the grid, we can also see that as the tens go up by 1, the units go down by 1.

$9\times5=4$          $9\times6=54$        $9\times7=63$            $9\times8=72$

45: $4+5=9$            54: $5+4=9$              63: $6+3=9$                72: $7+2=9$

10 Times Table: We just put a 0 on the end of the 1 times table! $9\times10=90$.

11 Times Table: You put 2 of what you multiply together:

$$3\times11=33$$

$$6\times11=66$$

When multiplying by 10, put a 0 on the end. No tricks for $11\times11$ and $12\times11$, just need to learn them.

12 Times Table: Split the 12 times table in to the 10 times table  and the 2 times table.

$$6\times12=6\times10+6\times2=60+12=72$$

$$3\times12=3\times10+3\times2=30+6=36$$

$$12\times12=12\times10+12\times2=120+24=144$$

We can use our knowledge of times table and inverse operations to help with each other.

What is $35\div7$?

We can turn it into a multiplication question.

$$\_\_\times7=35$$

$$7\times5=35$$

$$35\div7=5$$

## Example Questions

$$7\times7=49$$

$$12\times11=11\times10+11\times2=110+22=132$$
